Essay: The Role of Reaction Rates in Industry and Daily Life Task 2 from the section covering paragraphs 18–20

In daily life, we use refrigeration to decrease the kinetic energy of molecules, thereby slowing down the biochemical reactions and microbial growth that cause food to spoil. This "deceleration" allows for the long-term storage and global transport of perishables. For metals, oxidation (rusting) is a slow but

For metals, oxidation (rusting) is a slow but steady destructive process. By applying protective coatings like paint or using inhibitors, we decelerate the reaction between iron and environmental oxygen/moisture, extending the lifespan of infrastructure like bridges and buildings.

In industry, time is a critical resource. Many essential chemical processes are naturally slow and require catalysts or specific conditions to become economically viable.
